Abstract
The article presents data on the biological effectiveness of the use of the parasitic entomophage trichogram on corn crops to control the number of Helicoverpa armigera Hbn. In 2021, the average number of cotton scooper larvae was 7.4 per 100 plants. The double release of the trichogram on corn crops in 2021 made it possible to significantly reduce the number of phytophagous eggs. The biological efficiency of the first release of a parasitic insect averaged 42.6%, the second is 89.0%.
